After a spring rainstorm, these large strange-looking mushrooms can often be seen in grassy areas. They appear as single individuals or multiple scattered individuals. At first, the body resembles a golf ball, with a white smooth surface. Then, it gradually becomes darker. Once mature, the dark brown exterior starts to crack, revealing a purplish-black interior. At this time, it releases purplish-brown spores. During its growth process, it undergoes dramatic changes in its appearance.
